Identifying Year Of F134

Afternoon guys, new to this place. I have our 1956 CJ5 that we have owned since new, I know at one point my great uncle replaced the engine with another F134, or atleast my dad thinks he did. Is there a semi accurate way to determine what year the engine is? Behind the water pump on the engine deck it is there is 3 letters that are hard to read then the numbers 166-67. I am sure I will be on here alot reading and asking some stuff, starting the restoration of it.

 

Welcome.

The PCV (crankcase venting) plumbing varied on different models and years. I know what a '56 CJ looks like, but uncertain on the others.

Got pictures?

 

Here is a p ic

 

here is another view

 

Some reason my pics aren’t loading, anyways the stampings on the deck are DSF 166-67

 

The PCV system has been 'customized' but the vent on top of the rocker cover is not like my OEM 1956. Several patterns were used at different times and on different models.

The single action fuel pump (no vacuum) would be a later variant, but easily could have been swapped.

The dashpot on the carb is a later evolution, but I don't know the exact applications.

An OEM 1956, the oil filter would have been a canister mounted on the block, just forward of the oil fill tube.

 

That is the engine serial number.

 

Looks pretty late to have the emissions junk on the carb definitely after my 1960.

 

I understand totally, I know this isn’t the original 56 motor, was just curious if there was a good way to determine the rough vintage of the engine. I think it was late 60’s early 70’s. Our family is from the UP and my great uncle worked for a large copper mine, he mentioned they repowered all the jeeps at the mine with Perkins engines and he bought the gas engines they pulled when they were new.

 

Starting in ‘64, Kaiser started using a “spin-on” oil filter instead of the canister filter. Both styles were bypass filters mounted up top ahead of the carb, and used small oil pipes. Do you have the oil filter assembly?

Just the spin on one that was on the engine, there were a fair amount of things changed over the years on ours, but looks like it’s been a spin on since this engine has been in the Jeep whenever they dropped this one in

 

That is an interesting serial number. The only 60s engine serial number prefix I was familiar with was 4J for a CJ or MD for a M38a1. I wonder if this was an industrial engine prefix for equipment not intended for highway use?
